2 Claims. (or. 206 '1.5

This invention relates to a keyless look.

I While the particular lock selected for i1lus-- tration is described in connection with a. box such as a tool box or the like, it is to be understood that the lock of the present invention may be or other receptacle securely in closed position,

and which look at the same time may be readily released or opened secretly and with little effort by a person familiar with the same, but is dificult to release or circumvent by an unauthorized person or by aperson unfamiliar with the combination of movements required to release the lock.

Another and more specific object of my invention is to provide a keyless lock requiring a combination of different movements in different directions to release the same, and a lock with which these releasing movements may be imparted within the view of other persons without revealing to them in openingthe lock the combination of movements required for that purpose.

Another object of my invention isto provide in a keyless lock, prefer-ably of a character requiring two or more different predetermined move-- ments in different directions to release the same, a counterweighted arm arrangement which may be employed to make an additional tilting movement necessary to release the lock, thereby lending additional security, and which counterthe hinge connections between the box and the cover;

Figure 8 is a fragmentary perspective View of the locking member which is applied to the box;

and V other container or the like, formed, for instance,

of wood or other suitable material. The box, indicated in' its entirety, atv 5, has front and rear walls 6 and l, end walls 8 and, 9, and a suitable bottom ll]. f

The cover, which is indicated in its entirety at I 2, is shown of hollow form and has a top wall weighted arm arrangement may be secured in 7 released position where the additional security afforded thereby is not required. 7 v

It is also an object 'of my invention to provide a keyless lock of the character described which is of simple and inexpensive construction and which may be operated conveniently and effectively; also, a lock of the character described composed of few parts and adapted for convenient assembly and application to the members to be locked thereby-for instance, to a box or other container and to the cover therefor.

Further objects and advantages of my invention will appear from the following detailed description, taken in connection with the accom-' 13, front andrear walls and I5, and end walls l6 and H. When the cover I2 is closed, the Walls [4, l5, I6, and I! thereof'register with the walls 6, 1, 8, and 9, respectively of the box 5. The cover I2 is mounted upon the box 5 in such a manner as to permit swinging and longitudinal movement of the cover relative to the box;

A pair of hinges l8, l8 mount the cover l2 for swinging and longitudinal sliding movement othersecured to the box 5. These hinge members l9 and 20 have cooperating hinge knuckles 21 and 22 pivotally joined by a rod or'pintle 23. Clearanceis provided, as indicated at 24, between the hinge knuckles 2| and the hinge knuckles 22,

so thatthe cover is slidable relative to the box.

in a longitudinal direction or along the hinge. The cover I2 is shown in Figure 3 as shifted to its released position toward the left. Any other mounting of the cover which will permit swinging and sliding movement of the cover relative to the box in the mannerset forth may be employed within the scope of the present invention.

pivotally and slidably connected to the box 5 may be provided for limiting the opening movement of the cover and, if desired, for holding the cover in open position.

A slotted strut 25 pivoted'to the cover I 2 and arm 50 is not necessary, this arm 5|] is adapted to be swung in a clockwise direction about its pivot, as the device is viewed in Figure I, to clear the lug 52 of the recess 54, and may be secured in this position by inserting a pin 58 through an opening 60 in the housing 45 and through the The lock comprises a generally hook-shaped I stance to the inner side of the front wall 6isublocking member 30 secured to the box 5, for in- I stantially intermediate the endsrthereof, and a a v cooperating and generally hook-shaped locking member Secured t0 t e cover l2, for instance, to the inner ide of the front wall |4 substan:

tially intermediate the ends of this wall. When; the cover is closed, the locking member 30 engages'the'locking member 3| to lock'thecover in closed position. The lockingmember 30, has

an integral lug 32 which cooperates with an integral lug 34 on the locking member 3| tolock the member 3|- and, thereby the cover l2 against movement relative to the member 30 and the vbox V5 in the longitudinal direction indicated-by the arrow 36 in Figure 1.-1 The-lugs 32' and 34 have .inclined suriaces'3l and 38. r Y

The loek, as thus 'far'described, is releasedrby pressing or shiftingtheylocking member in:

wardly. slightly relative to the locking member 3 l, for instance from the locking position shown in Figure 5 to the position shown in-Figure 6. This shifting movement, which is -in-th'e direction indicated by the arrow 4|l in-Figure 1, may be accomplished by pressing the intermediate per-9 tion; of the front wall 6 of the'box inwardly slightly relative tothe 'cover |2 inthe direction indicated by the arrow 40. 7 This frees the lug opening 65 provided at the upper end of the arm 50 to maintain the lug 52 in retracted or released po'sitionagainst the action of the counterweight 53. A spring arm 62, secured at one end; at 64 tothe inner side of the front wall ID of the box 5, is adapted tobeengaged at its opposite or free end with the inner headed end 58' of the pin 58 to hold the same in the position in which it maintains the lug 52 released. The attachment f the spring arm 62 to the box 5, at 64,-is preferably of a pivotal character to permit this'arm 62 to be swung downwardly clear of the pin 58 when it is desired to release the pin and when the pin is not in place.

The pin-58 .may'be carried by a cord, flexible fire or-other flexible element 68 which maybe securedat.69;-.for1instance, to the inner side of theifront wall, ||l of the box. Aspring arm I0, secured at 112' to the inner side of the end wall "9 of the box .5, cooperates yieldingly with the inner side ofthe end wall ILofthe cover |2 to shift the cover back to the right (FigureB) to bring the end walls of the cover intoregistration with the 34 from the lug 32 as shown in Figure 6; and

then, bypressing or'shifting the cover |2 endwise or longitudinally slightly relative to the-box .5 in the direction indicated by the arrow 36,

the lock is-released sothat the cover l2 may be swung to open position.

end wallshof the box, upon swinging the cover |2 to closed position A spring-pressed plunger I5 carried by a bracket 16 secured, for instance, to the housing t5 isadaptedto cooperate with a bracket on the loweredge ofthe frontwall M of the cover, or

directly with this lowerl edge" of the wall M to impart the initial movement of the cover to open position when thelock is released. The spring 18, whichurges the plunger 15 yieldingly in an The locking meanson the box 5 is preferably enclosed within a metal housing which may a y 45 for instance at 46 and 46'. Where a housing such as the housing 45 isemployed, thelocking bes ecured to the inner sidefof the front wall is member 35 may be secured to this housing at 48,

being thereby secured with the housing 45 to-the box 5 in the position described To give the lock greater security, an arm 50 upward 'direction,is coiled about the plunger and interposed between the lower arm of the bracket the viewlof otherswithout revealing tothem in is pivoted at 5|, for instance, to the housing :45

and, thereby on the front wall 5' of the-box. This arm has a lug 52 which is held by meansof a counterweight 53 in the position shown in Figure 1 to lock the head or lug 34 on the bolt or looking member 3| in the recess 54 inthe bolt or looking member 30 and against'disengagement from the lug 32 for longitudinal movement of the .cover relative to the box; 'I'he lug 52 is released or moved clear of the lug 34 bytilting or lifting the right hand end of the .box, 5 as the sameis viewed in Figures 1, 2, and 7 upwardly until the arm 50 swings in a counterclockwise direction (Figure '7) about its pivot=5| sufficiently to clear the lug 52 of the recess 54. Y

opening the lock the combination of movements 1 required forthat purpose. ,The lock' securely locks the cover of the box in closed position and,

The locking membersi30 and 3| are then re-" leased, as previously described, by pressingthe.

cover l2 longitudinally to the left to; free the hooked lower end of :the lockingmember 3| from the hooked upper end of the locking memberv30, whereupon the cover-l 2 is adapted to be swungto 'open position. p I Where the additional securityaffordedby-the 'at the same time, may be readily released or opened secretly and with'little effort by a ,person .familiarwithkthe same, but is difiicult to release or circumvent by an unauthorized person or by va person unfamiliar with the combination of movements required to release the lock.

The particular lock selected for illustration requirestwo different predetermined movements in differentdirection's xto release-the same, and has which, when operative, malcesan additionaltilting movement necessary to release the lock,

thereby lendingadditional security. 'This counterweighted arm arrangement may be secured front wallof thebox5 inwardly and shifting the 7 different persons may belrele'ased" by differentingrelease'd positionwhere this additional securityis not required. It is ,to' be understood that other combinations .of movements may be employed within the scope of the present invention, so thatdiiferent locks in thehands of the counterweighted 9 arm arrangement counterweighted arm arrangement, instead of being adapted to be released by lifting or tilting the right hand end, may be arranged to be released by lifting or tilting the opposite end, or by lifting or tilting the back or front of the box,

and the relative direction of shifting movement between the cover and the box may be varied, as may be the particular movement illustrated as required to release the locking members to permit shifting of the cover longitudinally relative to'the box. i

I have described the invention in connection with the details of a particular embodiment, but I do not intend thereby to limit the invention to such details, nor do I intend to be limited to the particular use and relation of the essential features shown and described.

I claim:

1. In combination, a box, a cover hinged to one wall of said box for swinging movement to open and closed positions and movable relative to said box axially along the hinge, a first locking member mounted on the opposite wall of said box and having a recess and a hook-shaped lug overhanging said recess, a second locking member mounted on the wall of said cover opposite the hinge and in alignment with said first locking member, said second locking member having a recess for receiving the hook-shaped lug of said first locking member and a hook-shaped lug underlying said recess and adapted to enter the recess in said first locking member for interlocking engagement wtih said first locking member to hold said cover in closed position, a second lug on said first locking member and cooperating with said second locking member tohold the hook-shaped lug thereof in interlocking engagement with the hook-shaped lug on said first locking member and said cover against movement relative to the box axially along the hinge, said second lug being adapted to be released from cooperation with said second locking member by pressing the adjacent wall of the box inwardly whereby said cover is freed for movement relative to the box axially along the hinge to release the interlocking engagement between the hook-shaped lugs on said first and second looking members so that the cover may be swung to open position about the axis of said hinge, and an arm pivoted internally of said box on the adjacent wall of the box and having a counterweight for holding a portion of the arm over the recess in said first locking member to hold the hook-shaped lug on said second locking member against disengagement from the second lug on said first locking member when the adjacent wall of the box is pressed inwardly, said counterweight being operable to move said arm clearof the recess in said first locking member by im parting tilting movement to the box.
